A 32-year-old female presented with a rare case of pituitary abscess manifesting as homonymous hemianopsia. Serum prolactin level was slightly high (40.8 ng/ml). Magnetic resonance (MR) imaging showed the content of the lesion as homogeneously isointense on the T_1-weighted images and hyperintense on the T_2-weighted images. The capsule of the lesion, which appeared thin and smooth, was enhanced by gadolinium. Dural enhancement around the sella turcica was also recognized. Thallium-201 single photon emission computed tomography (^<201>Tl SPECT) showed homogeneous high accumulation in the pituitary region on both the early and delayed images. The lesion was treated via a transnasal-transsphenoidal approach. The cystic lesion contained pus and the capsule consisted of normal pituitary gland with inflammatory changes. The patient was treated with antibiotics for 3 weeks and the pituitary abscess was cured completely. Pituitary abscess can be differentiated from pituitary adenoma as lesion with a homogeneous high uptake on ^<201>Tl SPECT on both the early and delayed images, and no enhancement of the central portion on MR images.
